I use a Truball Copperhead. The Sabertooth is actually made by Scott and it's avery good release. The only issue I've ever had is with a Velcro strap. Get a buckle strap and also shoot a few to see what you like.Both of these are double caliper releases. Scott also makes single caliper releases but I have no experience with them.

Ipersonally like adjustable length releases like the Sabertooth and Copperhead. You can adjust the very short so that youwill have a good anchor point on your cheek and not back by the ear like thebarrel releases.

Attaching the copperhead to a D-loop or string is a breeze. You squeezein onthe trigger and the jaws open up. Some others do not connect this way.
